Under the current digital television transition, television stations in Mandatory Markets, in Canada are launching digital transmissions by August 31, 2011. On August 18, 2011, the CRTC issued a decision that allows CBC's mandatory market rebroadcasting transmitters in analog remain on-air until August 31, 2012. Where known, a digital channel assignment is noted below. Digital channels listed on a green background have already been launched, while those listed on a red background have not yet commenced operations. In some cases, the digital channels have been allocated but the stations have not applied to use them; as there is no requirement that Canadian stations begin digital broadcasts before the end-August 2011 analogue shutdown, it is currently unknown whether some broadcasters will ask to flash-cut on their existing frequencies or to continue on their assigned digital channel.
